Extending lamp life
The projection lamp is a consumable item that normally can last up to 3000-4000 hours
with proper usage. To keep the lamp life as long as possible, you can do the following
settings via the OSD menu.
• Setting Lamp Mode as Economic or SmartEco
Using Economic mode reduces system noise and power consumption by 30%. Using
SmartEco mode reduces system noise and power consumption by up to 70%. If the
Economic or SmartEco mode is selected, the light output will be reduced and result in
darker projected pictures.
Setting the projector in Economic or SmartEco mode also extends the lamp operation
life. To set Economic mode, go into the SYSTEM SETUP: Advanced > Lamp
Settings > Lamp Mode menu and press / .
• Setting Auto Power Off
This function allows the projector to turn off automatically if no input signal is detected
after a set period of time to prevent unnecessary waste of lamp life.
To set Auto Power Off, go into the SYSTEM SETUP: Basic > Operation Settings
> Auto Power Off menu and press / . The time period can be set from 5 to 30
minutes in 5-minute increments. If the preset time lengths are not suitable for your
presentation, select Disable. The projector will not automatically shut down in a certain
time period.
